[ofa-general] iw_cxgb3.ko needs unknown symbol dev2t3cdev

[Brian J. Murrell]

When I run a depmod -ae -F <System.map> on my resulting installation of
OFED 1.3 I get the following error:

WARNING: /lib/modules/2.6.18-53.1.14.el5_lustre.1.6.4.55.20080411125046smp/kernel/drivers/infiniband/hw/cxgb3/iw_cxgb3.ko needs unknown symbol dev2t3cdev

What I can't seem to figure out is why this symbol is not being exported
by kernel/drivers/net/cxgb3/cxgb3.ko.  The source shows it being defined
and exported in drivers/net/cxgb3/cxgb3_offload.c:

/* Get the t3cdev associated with a net_device */
struct t3cdev *dev2t3cdev(struct net_device *dev)
{
	const struct port_info *pi = netdev_priv(dev);

	return (struct t3cdev *)pi->adapter;
}

EXPORT_SYMBOL(dev2t3cdev);

However the resulting cxgb3.ko clearly does not have it defined:

# nm /lib/modules/2.6.18-53.1.14.el5_lustre.1.6.4.55.20080411125046smp/kernel/drivers/net/cxgb3/cxgb3.ko | grep dev2t3cdev
#

My build output shows the build of cxgb3_offload.c and the linking of it
into cxgb3.o:

Any ideas what the problem could be?
